Introduction:Physical therapy and peritendinous hyaluronic acid (HA) injections have both shown promising results in the treatment of shoulder tendinopathies. However, the superiority of treatment combining physical therapy and HA is unclear.Objectives:In this parallel-group, randomized, controlled trial, we investigated the efficacy and safety of peritendinous injection of HA in patients with persistent supraspinatus tendinopathy. To this end, we compared the therapeutic outcome of treatment with HA as an adjuvant to physical therapy with that of physical therapy as sole therapeutic intervention.Methods:84 Patients with ultrasound-confirmed supraspinatus tendinopathy were randomized to receive either physical therapy + subacromial HA injections or physical therapy only. Treatment efficacy was assessed using a Visual Analog Scale (VAS) for pain and an Activities of Daily Living (ADL) scale.
